Figure 2From: Production of the short peptide surfactant DAMP4 from glucose or sucrose in high cell density cultures of Escherichia coli BL21(DE3) Growth profiles, product accumulation and extracellular metabolite profiles for batch cultivation in chemically defined medium (CDM) with (a) glucose (CDM G ) or (b) sucrose (CDM S ) as sole carbon source for induction performed at DCW m . Biomass formation (DCW, circles) is reported on a logarithmic scale; product accumulation (DAMP4, open squares), substrate concentration (SS, open triangles) and acetate accumulation (Ac, inverted filled triangles) are shown. The point of induction is indicated by a dashed vertical bar. Experimental error represented as SD, n ≥ 2.Back to article page
